Biband#
The Biband
measures the cumulative bandwidth and message rate
values. To achieve this, the first half of ranks communicates with the
second half using MPI_Isend/MPI_Recv/MPI_Wait
calls. In case of the
odd number of processes, one of them does not participate in the message
exchange. The bunch of MPI_Isend
calls are issued by each rank in
the first half of ranks to its counterpart from the second half of
ranks, and vice versa. The number of messages issued at each iteration
step is defined with the MAX_WIN_SIZE
constant. The same buffer is
used for every send event in the iteration.
